The InnerShaft and Aluminum Main Rotor Hub for Blade CX is designed to improve the strength of the stock innershaft and stock plastic main rotor hub. The new innershaft and main rotor hub includes a new strong steel innershaft, a bigger and stronger steel spindle shaft and a precision CNC aluminum main rotor hub. This system not only reduces the chance of broken main rotor hub and innershaft but also provides a new great look for your Blade CX.
